DETAILED DESCRIPTION

Some embodiments of the present disclosure relate to improvements to voltage multiplication of a direct current (DC) signal to an alternating current (AC) signal within an electronic device to provide the AC signal to an external device (such as AC mains). For example, a voltage multiplication circuit may include a high-voltage converter integrated circuit (IC) and a low-voltage power controller IC. The high-voltage inverter IC may receive an input DC signal at V_(IN) and may output an output an AC signal at V_(OUT) to the external device. The high-voltage converter IC may include multiple stages of boost and/or inversion so as to output the AC signal at an appropriate level for an external device. In some embodiments, a boost regulator circuit may receive the input DC signal at V_(IN), a duty clock signal, a reference signal at V_(REF), and a second intermediate DC signal at V_(INT2) and may output a first intermediate DC signal at V_(INT1) based on the duty clock signal and a comparison of V_(REF) and V_(INT1). In these and other embodiments, V_(INT1) may be greater than V_(IN). Additionally or alternatively, the boost circuit may adjust V_(INT1) so that V_(INT2) approaches V_(REF).

In some embodiments, a voltage converter circuit may receive the first intermediate DC signal at V_(INT1) and a clock signal and may output the second intermediate DC signal at V_(INT2) based on the clock signal and V_(INT1), V_(INT2) may be greater than V_(INT1). In these and other embodiments, the boost regulator may operate in a regulated state and the voltage converter circuit may operate in an unregulated state. Likewise, a voltage driver circuit may receive the second intermediate DC signal at V_(INT2) and may output the AC signal at V_(OUT) based on the second intermediate DC signal at V_(INT2). In some embodiments, the boost circuit may adjust V_(INT1) so as to cause V_(INT2) to approach V_(REF) which may cause V_(OUT) to be output to the external device at the appropriate level.

In some embodiments, the low-voltage converter power controller IC may control the high-voltage IC so as to cause the high-voltage IC to output V_(OUT) at the appropriate level. For example, the low-voltage IC may provide the duty clock signal to the boost regulator so as to control a configurable duty cycle (e.g., 50%) of components within the boost regulator. Likewise, the low-voltage IC may provide the clock signal to the voltage converter circuit so as to control a frequency of a clock rate within the voltage converter circuit. Additionally or alternatively, the low-voltage IC may determine a current of the first intermediate DC signal and V_(OUT) and may adjust the duty clock signal based on the first intermediate DC signal and V_(OUT).

The system may be configured to increase power efficiency, increase accuracy of the AC signal and V_(OUT) over a wide range of power levels of the input DC signal. Likewise, the system may allow design and implementation of a cheaper and smaller chip.

Various embodiments disclosed herein relate to an inverter supply system on a chip (ISSoC™), which may include a micro-inverter and may be suitable for DC-to-AC grid tied power inverters. A multi-chip module (ISSoC) may include connectivity with a smart meter via, for example, wire and/or wireline communication to provide power grid operators visibility and command and control to divert photovoltaic (PV) generated electricity from, for example, micro generation sites to grid use in a case of demand response. According to various embodiments, an ISSoC may increase efficiency of PV components and/or electric vehicle (EV) components (e.g., inverters) (e.g., to over 97%). Further, in some embodiments, an ISSoC may track an amount of micro generation electricity in real time and provide command and control functions (e.g., to avoid grid failures).

In some embodiments, a micro-inverter, which may use capacitor banks for boosting the power and current, may be sized (e.g., sufficiently small) to be mounted inside a PV panel, and may include measurement, communication, and control features.

Embodiments of the present disclosure are explained with reference to the accompanying drawings.

FIG. 1 illustrates an example system 100 of electrical components configured for voltage multiplication, in accordance with one or more embodiments of the present disclosure. The system 100 may include IC 110 and an IC 120 coupled to IC 110. IC 110, which may include a high-voltage converter IC, includes a boost regulator (also referred to herein as a “voltage boost circuit”) 112, a converter (also referred to herein as “muxcapacitor converter,” “muxcap,” or a “voltage converter circuit”) 114, and a driver (also referred to herein as a “voltage driver circuit”) 116, which may include an H-Bridge. In some embodiments, the converter 114 may include N-Channel switches such as switches using metal-oxide-semiconductor field-effect transistor (MOSFET), metal-semi conductor field-effect transistor (MESFET), double-diffused metal-oxide-semiconductor (DMOS), complementary metal-oxide-semiconductor (CMOS) silicon on insulators (SOI), semiconductor super junction (SJ), and/or Gallium Nitride (GaN) technologies. As depicted, the converter 114 may be coupled between the boost regulator 112 and the driver 116. According to some embodiments, the converter 114 may include a switch capacitor voltage divider circuit as described in U.S. Pat. No. 9,673,717, entitled “Electrical Circuit for Delivering Power to Consumer Electronic Devices,” filed on Jan. 15, 2016, the contents of which are incorporated by reference.

Further, IC 120, which may include a low-voltage power controller IC, includes a voltage/current sensor 122, a central processor unit 124, a maximum power point tracking (MPPT) controller 132, an I2C serial interface 134, a controller (also referred to herein as a “muxcapacitor controller”) 136, a memory management unit 138, NVSRAM 142, and SRAM 144.

In some embodiments, the boost regulator 112 may be configured to receive the input DC signal at voltage V_(IN) and a duty clock signal. In these and other embodiments, the boost regulator 112 may convert the input DC signal to an intermediate DC signal at voltage V_(INT1), which may be greater than voltage V_(IN). Additionally or alternatively, the boost regulator 112 may receive the duty clock (e.g., from voltage/current sensor 122), which may control a duty cycle of components within the boost regulator 112. In some embodiments, the boost regulator 112 may receive a second intermediate DC signal at V_(INT2) from the converter 114. In these and other embodiments, the boost regulator 112 may also receive a reference DC signal at voltage V_(REF), which may be a voltage that voltage V_(INT2) is to be equal to or similar to.

Additionally or alternatively, the boost regulator 112 may output the intermediate DC signal so that voltage V_(INT1) is greater than voltage V_(IN). Likewise, the boost regulator 112 may output the intermediate DC signal at the second DC voltage. In these and other embodiments, the second DC voltage may be a voltage that the voltage V_(INT1) is to be equal or similar to.

In some embodiments, the converter 114 may be configured to receive the intermediate DC signal at the second DC voltage. In these and other embodiments, the converter 114 may invert the intermediate DC signal at the second DC voltage to an intermediate AC signal at a first AC voltage. In these and other embodiment, the converter 114 may output the intermediate AC signal at the first AC voltage. Additionally or alternatively, the driver 116 may be configured to receive the intermediate AC signal at the first AC voltage. In some embodiments, the driver 116 may convert the intermediate AC signal at the first AC voltage to the output AC signal V_(OUT) at the second AC voltage.

In some embodiments, the voltage/current sensor 122 may be configured to receive a current signal from boost regulator 122, and provide a duty clock signal having a selectable duty cycle (e.g., 50% duty cycle) to the boost regulator 112. Further, the voltage/current sensor 122 may be configured to receive a voltage sense signal from the driver 116. The voltage/current sensor 122 may further be configured to output a digital current sense signal to MPPT controller 132, and controller 136 may be configured to output a digital frequency control signal (also referred to herein as a “clock signal”), which may be received by the converter 114.

In at least one contemplated application, IC 110 may receive an output signal (e.g., a voltage signal) of a solar panel and provide high-current and voltage boosting with the use of the boost regulator 112. In some embodiments, the boost regulator 112 may be programmed based upon the application and may use pulse-width modulation (PWM) to regulate an output voltage (e.g., V_(OUT)). Further, the converter 114 may use switched-capacitor and/or charge pump techniques to provide additional gain at high-efficiency. Further, the driver 116 may be configured to drive one or more phases of an external LC network for generation of the output voltage.

In accordance with various embodiments, the IC 120 may provide sensing and control functions that may be required by IC 110. For example, voltage and current may be sensed and digitized by IC 120 for use by MPPT controller 132, which may be configured to enhance the efficiency of the converter 114. In some embodiments, an embedded micro-processor may dynamically manage the converter 114 to regulate an output voltage (e.g., V_(OUT)) and optimize efficiency for each mode of operation, from the initial application of power, to the normal operating mode or an ultra-low power sleep mode (e.g., less than one milliwatt standby). On-chip volatile and non-volatile memory may also be provided for the CPU 124, which may include application-specific firmware that may be required by an end product (e.g. regulation, control, communication, etc.).

The I2C serial interface 134 may be configured to provide user programming, debugging, and control. Thus, in some embodiments, an output of a communication port (e.g., of an ISSoC) may be accessible (e.g., visible) (e.g., to a homeowner and the power grid) (e.g., to an electric vehicle driver and a computer located within the electric vehicle) such that actual electricity generation may be tracked in real time, and power may be diverted to a specific portion of the grid (e.g., during a demand response initiative by a grid operator).

FIG. 2 illustrates an example boost converter circuit 200 that may be used in the example system of FIG. 1, in accordance with one or more embodiments of the present disclosure. For example, the boost regulator 112 of FIG. 1 may include the boost converter circuit 200 shown in FIG. 2. As illustrated, the boost converter circuit 200, which includes a switched inductor boost converter, includes an inductor L1, a diode D1, a comparator 250, a pulse control unit 260, and a switching element (e.g., a MOSFET) M1. Pulse control unit 260 may include, for example, a servo loop control circuit.

The boost converter circuit 200 is configured to receive the voltage V_(IN) and the voltage V_(INT2), and output the voltage V_(INT1). In some embodiments, the voltage V_(IN) may be boosted and charge transferred from the input to the output by the switching element M1. High efficiency may be obtained with the use of pulse-width modulation (PWM) control of the switching element M1. Pulse control unit 260 may be configured to sense the output voltage of a voltage converter circuit (e.g., converter 114; see FIG. 1) and control the configuration of switching element M1 to enhance power efficiency while regulating the output voltage (e.g., voltage V_(INT2)).

FIG. 3 illustrates an example voltage converter circuit 314 that may be used in the example system of FIG. 1, in accordance with one or more embodiments of the present disclosure. For example, converter 114 of FIG. 1 may include voltage inverter circuit 314. The voltage converter circuit 314 includes a converter stage 315 and capacitors C1-C4. The voltage converter circuit 314 is configured to receive a clock signal f_(CLK) (e.g., from controller 136 of FIG. 1) and the voltage V_(INT). The voltage converter circuit 314 may further be configured to generate the voltage V_(INT2).

In some embodiments, the voltage converter circuit 314 may utilize switched-capacitor and charge pump technology to provide additional gain for voltage multiplication. Further, some embodiments may be suitable for high-voltage applications, and may achieve, for example, 98% power efficiency or more from no load to a maximum current load. In addition, the voltage converter circuit 314 may be digitally configurable to provide multiple gain and attenuation ratios and may be configured to meet, for example, the wide range of solar panel vendor requirements. According to some embodiments, high-voltage switches, their gate drivers, and support circuitry may be integrated on a high-voltage DMOS or super-junction semiconductor foundry process, thus reducing the bill of material cost as compared to conventional switched inductor based solutions. Likewise, high-voltage switches, their gate drivers, and support circuitry may be integrated on a CMOS or GaN semiconductor foundry process, thus reducing the bill of material cost as compared to conventional switched inductor based solutions. Moreover, the external capacitors (e.g., capacitors C) may include low-cost ceramic capacitors available from component vendors.

Since regulation of a micro-inverter may be provided by a switched inductor boost converter, in some embodiments, an converter (e.g., converter 114 of FIG. 1) may be configured as an open loop and may be un-regulated, which may increase power efficiency. The power efficiency may be limited only by RDS_(ON) of one or more semiconductor switches, the IR drop of the interconnects, the dynamic switching losses, etc. For example, the gate to source capacitance of the switches may be in the 3 pF-5 pF range, and the fCV current may be approximately 4 μA/switch. Additionally, the gate to source capacitance of the switches may be up to NpF in some embodiments. According to some embodiments, to accommodate higher output currents, multiple voltage converter circuits may be connected in parallel for lower output resistance. Further, the fly back and hold capacitors may be shared among multiple branches. For example, for a 7 switch, 5 parallel branch voltage converter network, the dynamic current (overhead current) may be approximately 700 μA, which may reduce the power efficiency by less than approximately 0.29%. Additionally, capacitors C1-C4 may include one or more capacitors. For example, capacitor C1 may include two capacitors, capacitor C2 may include four capacitors, and capacitor C3 may include seven capacitors.

FIG. 4 illustrates a graphical representation of a simulation of micro-inverter output power versus efficiency, in accordance with one or more embodiments of the present disclosure. More specifically, FIG. 4 shows the power efficiency of the DC/DC booster across an output power range. The output voltage was increased to 375V DC from 32V DC with +/−1% load regulation. In this example, a load current of 100 mA to 10 mA was applied to a single voltage converter stage.

As disclosed herein, various embodiments relate to a converter suitable for high-voltage applications (e.g., 100V-400V) and may provide more than 97% power efficiency from no load to a maximum current load. Further, the inverter may be digitally configurable to provide multiple gain and attenuation ratios and may be programmable for various applications, such as to meet a wide range of solar panel vendor requirements.

In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.

Terms used in the present disclosure and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” among others).

Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations.

In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc.

Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”

However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.

Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms “first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.

All examples and conditional language recited in the present disclosure are intended for pedagogical objects to aid the reader in understanding the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Although embodiments of the present disclosure have been described in detail, it should be understood that the various changes, substitutions, and alterations could be made hereto without departing from the spirit and scope of the present disclosure.
